Hello Rodrigo There are various ways to show the status of interfaces and each command provides different information and in different formats. The command initially chosen by Rene is the `show ip interface brief` will show the status and protocol of **all** the interfaces in a list, so you get a general picture of all interfaces with one command. If any of those interfaces are configured with IP addresses, those are also displayed. The `show interface fa0/x switchport` command will show the switchport configuration **of a single port in detail**. This can be used when the only information you’re looking for is about that port in particular. There is also the `show interface status` command which will provide a list of all the interfaces and include a column that shows the VLAN on which they are assigned if they are access ports, or if they are trunk ports, the word `trunk` will appear in that column. This command shows all the interfaces including the operational mode in which the ports are functioning. I hope this has been helpful!
